That's what I've been thinking about doing in conjunction with the m-sport 14mm rear bar. The front bar does have that tappered down center section which the M3 bar doesn't though. I'm curious to hear thoughts or experience on adding the M3 front mount bushings to zsp bar. Did you do that?

Except it takes about 5 hours of labour to do that... if you are in there, dropped the subframe and all that, you might as well put the M3 bar in right?

You waaaaaaaaaaaay off if you're talking about the rear bar. The stock bar is 13mm, the BMW performance bar is 14mm and the M3 bar is 20mm. From 13 or 14mm to 20mm is a HUGE difference.

one thing to remember about the front, the middle section drops down in size, the M3 front does not. minor as it is, it will cause more deflection. If you can find a cheap used M3 bar with the bushings, it does make a difference and the install is fairly easy.

I installed the M3 rear sway bar first, as i have the m-sport coupe and noticed it wasn't properly balanced going hard into corners the back was perfect but the front had more body roll,so i installed the M3 front bar and what a difference the car is nicely balanced and the front is anchored down and it is a big difference in conjunction with the M3 tension struts.
You get more feel through the steering wheel because of the M3 sway bar bushings. Money well spent on M3 sway bars. Highly recommended.

Do the M3 bars understeer still? Did you do the M3 tension arms and wishbones in the front? I highly recommend those... really nice - no cons - none.

Yes did the tension arms and wishbones before the sway bar install. Understeer almost eliminated.

thread revival!
The Eibach sway kit has "Greasable Urethane Bushings For Increased Responsiveness" i assume that is stiffer than OE (335d m sport) or would you think it is worth changing the bushings that come with Eibach? |

I started with a M3 front say bar on the 335i I had.
Afterwards I installed a full Eibach sway kit (replaced the front M3 with the Eibach) and it made a very noticeable good difference. Car would corner flatter and feel a bit sharper. The Eibachs are also not hollow, they are solid. |

I have a non-sport E90 but has the front sway bar, I'm not sure if I have the rear sway bar. If I did have the rear sway bay. Should I might as well change the bushings to M3 ones?

Hi, just thinking about doing an upgrade of sway bars on my E91 325i.
I want to install suspension Bilstein B12 and thinking also about sway bars upgrade. Would you recommend used M3 sway bars with M3 bushing? Recently I found also H&R sway bar set 27 and 20mm but of course not very cheap. I'm just not sure what would be better option and result in better control of the car and not loosing all the comfort as well. |
